CZ290818B6 - Process for producing incrusted products of stone, particularly marbles - Google Patents

Abstract

The proposed process by which rough cut stone, particularly marble, is joined by a layer of binding agent to a substrate slab, is based on the fact that the upper layer of this rough cut stone, connected with the substrate slab by highly adhesive glue, is cut back and/or polished to the required thickness or profile along the length of the substrate slab.

Description

A method of making incremented stone products, especially marble

Technical field

The invention relates to stone production of stone incrustations, in particular natural marbles, including large-scale products for the needs of construction, furniture and the like.

BACKGROUND OF THE INVENTION

The use of stone, especially marble and other natural trunks, for decorative purposes is well known in the construction industry. Blocks or rough slabs are cut from the stone block. The slabs are cut into tiles of various shapes, gravestones, cladding slabs and the like, the nature of the stone material, especially its high brittleness in relatively thin slabs and technical equipment, do not allow cutting stone into slabs thinner than 2 cm, especially in large areas Significant waste is generated during production, which reaches up to 50% loss of input natural material. The products of the boards thus produced have a relatively high weight, which limits the size of the usable surfaces of the boards and makes them difficult to transport; their practical application requires considerable physical strength. These facts make it difficult or even impossible to make wide use of the rare properties of the strain.

For decorative purposes, slabs made of crushed stone or stone fragments are also applied, which are applied to the bonding layer of the base plates, whereupon the uneven surface is coated with a layer of translucent or transparent material. These products cannot take advantage of the decorative effect of large areas of solid or solid stone and also have a large weight.

SUMMARY OF THE INVENTION

The known drawbacks are solved by the process for the production of stone incrustations according to the invention. It is an object of the present invention to cut the top layer of coarse cut stone bonded to the backing sheet with a highly adhesive adhesive along the length of the backing sheet and / or sand to the desired thickness or profile.

The invention makes it possible to use, for various purposes, stone slabs of relatively small thickness, optimally about 1 cm or less. This results in a substantial reduction in the weight of the products for large-area boards. Fixing the stone layer to the backing sheet with a highly adhesive adhesive makes it possible to use cutting and grinding technology for the production of large surface incremented products. The unwanted layer of stone is cut off and, if necessary, further sanded over all or part of the surface. Incrustated products can be used both in the construction industry, for example for wall and ceiling cladding, as well as in the manufacture of decorative furniture. There is no restriction on the possibility of creating stone shapes of different kinds, colors and textures using natural material drawing.

Application example

After cutting the raw material from the block or quadrate, the stone is qualitatively evaluated. Natural defects such as cracks, trimmings, nests and similarly prepared material are removed in the selected assembly on a base plate of a specified size and shape and form a stone layer on it. The stacked stone particles are close to each other, and the joints between the particles may be filled with a stone binder. The base plate material is determined depending on the purpose and use of the finished product. Suitable is glass, etemite, but also sheet metal, wood or particle board. Before the stone layer breaks, a layer of epoxy, acrylic or latex adhesive with highly adhesive areas is applied to the base plate. Allow the adhesive to set and harden

The thickness of the stone layer is reduced either by cutting it over the entire surface, if necessary only a part of it, thereby achieving an artistic effect, after which the slab is ground. The thickness of the stone layer can also be reduced directly by grinding. Depending on the need and purpose of the product, the board is further polished, seas and the like.

Claims (1)
